TeX Live and MacTeX ⇒ Windows 7 x64 installation directory trouble

[geoguy09]

Hi, after I mounted the iso image for TeXLive 2008 and attempted to install, the installer listed the default directory as not writable. I have attempted to change the path with some alternatives but with no success. My program file options are Program Files and Program Files (x86) for 32-bit apps. I could not find special install instructions for 64-bit Windows OS. Am I overlooking something? Default Tex Director is: C/Program Files (x86)/texlive/2008/. I have attached the installer listing.
Thanks.

Probably you need to start the installation process with administrator rights.


Best regards and welcome to the board

Thanks Thorsten. That did not work and I am using MagicDisc for disk image mounting, which has not given me any trouble with Win7. The recommended installation in the user guide does not work. I will download and attempt to manually install the tarball. Plus I'd like to try 2009 beta version. I installed MacTex 2008 flawlessly on my iMac, but plan to use Tex in a classroom for math and physical sciences note-taking. Plus, although I have known about Tex, but have never used it. I have some learning to do.

I can't advice any further. I did a successful installation of TeX Live 2008 on my notebook with Windows Vista Home Premium via internet. As far as I remember starting the installation process as administrator did the trick. I rarely use Windows and I did this installation only for testing purposes.

The problems you describe are not specific to 64-bit Windows but to UAC. Writing to "Program Files" requires admin privileges, but starting with Vista most programs are executed unelevated, even if your user account belongs to admin group. For "compatibility" Windows does some auto-detection and elevation of installer programs, folder and registry virtualization, ... and who knows what other voodoo. We haven't found any sensible way to work with that so far, so if someone has any suggestions, I'm all ears.
